Police found a 49-year-old man, but when they tried to arrest him, a short struggle took place. After calling in reinforcement to detain the combative suspect, officers were able to safely detain the man, investigators said.

The man was taken to the Sacramento County Jail to be booked and continued to be physically and verbally resistant once inside the jail facility, police said.

After officer took the man out of the patrol vehicle, the man became unresponsive.

Officials performed CPR, but the man did not respond. He was then taken to the hospital, where he was pronounced dead.

Sacramento police taped off one block in each direction of 19th and H streets to look for evidence.

It will likely take an autopsy to reveal why the man died and if he had a medical condition.
